The first I have seen this season - glad to have them back
This guy was really brave - almost walked too close for me to get a focus.

I like the walking pose and head angle. It looks a bit too contrasty on my monitor and the head is oversharpened. A lower angle would have made it even better and I might clone out the dark spot behind the bird and run NR on the BG.
Terry, was the image originally underexposed? I ask this because I see some colour noise on the chest/belly of the sanderling...typical of what happens when lightening shadows too aggressively. I agree with Axel on other points too (including the nice walking pose and good head angle), and would also give it back some canvas in front (if you have it).
Thanks for the very helpful suggestions. Looking back at the RAW file, it was underexposed. The bird was in shade and there was an overall greenish cast. I've made some changes that hopefully are an improvement, but couldn't incorporate all the suggestions. Hopefully I'll get another chance to see them again in better light.
